[time-nuts] AN/URQ-13 new thread clean up.

[paul swed]

Exciting. After opening the outer oven cylinder someone was in that section
before as the shock compound has been removed. And the failure appears to
be the inner oven heater is open.
A better description of the unit.
The FE-15a oscillator assembly is about 6" nd 3 sections.

Outer tuning caps and at 110 F it also contains the outer oven control
opamp for temperature.

Middle contains the inner oven control opamp and either oscillator buffer
or the oscillator. (Guessing buffer.)
The heater transistor appears bad/shorted.

Inner or deepest unit.
Covered with outer heater winding.
Suspect a inner heater winding Open
Perhaps the oscillator.

Going to find out.
Must unsolder the outer winding and a few screws.
Regards
Paul
